10. f8d6 Already an opening novelty. Robson was clearly surprised by the last move and spent a long time on his reply. 10... e6e5 Both 10...Ne7 and 10...Nh6 are good options. 11. d6e5  11... a6b4 This tempting move is a mistake. Black should choose either 11...Ne7 or 11...Nh6. 12. e2f4 The refutation of Black's play. Robson needs a lot of praise to find all this over the board, in a rapid game, with the pressure of being caught in the opening.
